Definitions
- This invention relates to a spacer which is used to set a distance between an adjustable stop member and a rotating gear in a power transmitting device.
- this invention relates to the use of a spacer which, when worn away, produces a running clearance between two parts in the power transmission device and the residue is non-deleterious to moving parts in a power transmitting device.
- the thrust screw is axially spaced from the side of the large gear or ring gear to limit axial deflection when the differential is loaded.
- the distance between the thrust screw and the ring gear must be controlled accurately to insure that deflections are kept within allowable limits.
- the difference between the thrust screw and the ring gear has been set using feeler gauges or shim stock with a thickness of 0.010 to 0.020 inches. This has been found to be a very time consuming process and has caused problems in assembly line production.
- the spacer of the present invention is bonded to the bottom of the thrust screw and abuts the ring gear.
- the spacer is made of a wearable material which is of a thickness equal to the 0.010 to 0.020 required running clearance. As the ring gear rotates, the spacer is worn away thus producing the required running clearance.
- the spacer which is made of a material such as carbon, disintragates producing residue that is non deleterious to bearings or gearing.
- a power transmitting device comprising a housing, a shaft rotatably mounted in the housing and a ring gear mounted on the shaft for rotation therewith.
- the ring gear is capable of deflecting in an axial direction under load.
- a stop member is fixed to the housing and has one end adjacent one side of the ring gear. The stop member limits axial deflection of the ring gear to prevent overstressing of the components.
- a spacer of a predetermined thickness is attached to the end of the stop member adjacent the ring gear and is in abutting contact with the ring gear.
- the spacer is formed of a material capable of wearing when contacted by the rotating ring gear and thereby provides a running clearance of the predetermined thickness between one end of the stop member and the ring gear. Consequently, the one end of the stop member will prevent the ring gear from deflecting axially under load a distance greater than the predetermined distance.
- the spacer is made of a material which is non deleterious to moving parts after being worn away.
- FIG. 1 is a cross sectional view of a power transmitting device including the present invention.
- FIG. 2 is an enlarged view of the thrust screw shown in FIG. 1.
- the device 10 includes a housing 12, a shaft 14 mounted on bearings 16 and 18 which are located in housing 12.
- a ring gear 20 is mounted on the shaft 14 for rotation therewith.
- a stop member 22 is fixed in the housing 12 and extends into the device to have one end adjacent one side of the ring gear 20.
- the power transmitting device is an automotive differential.
- the preferred stop member 22 used in the automotive differential is a thrust screw which is locked in position in the housing by jam nut 24.
- the thrust screw limits the axial deflection of the ring gear 20 under load conditions during normal operation of the differential.
- the gap or running clearance between the ring gear 20 and the stop member 22 which determines the amount of axial deflection allowed under load conditions is critical in that a gap too large would allow the build up of stresses in the ring gear and shaft.
- feeler gauges or shim stock has been used to set the critical distance between the thrust screw and the ring gear.
- the desired running clearance is between 0.010 and 0.020 inches.
- feeler gauges and shim stock to set this small gap is extremely time consuming and, consequently, makes the power transmitting device more expensive to mass produce.
- the present invention includes the spacer 26 bonded to the end of the stop member 22 which is adjacent the ring gear 20.
- the spacer has a diameter which is equal to or less than the diameter of the stop member.
- the spacer 26 is made of a material which is easily worn away when in rubbing contact with moving metal parts.
- the spacer is made of a carbon material which is the same thickness as the desired running clearance between the ring gear 20 and the stop member 22. It has been found that a graphite sheet, such as GRAFOIL, a registered trademark of Union Carbide Corporation, which has a thickness equal to the desired gap is an ideal material for fulfilling the functional requirements set forth above for spacer 26.
- the carbon spacer is bonded to the stop member or thrust screw 22 by an adhesive such as ethyl cyanoacrylate which is sold under the trade name of LOCTITE Super Bonder 495, a trademark of the Loctite Corporation.
- the stop member 22 Upon assembly of the power transmitting device, the stop member 22, including the spacer 26 bonded thereto, is assembled so that the spacer is in abutting contact with the ring gear 20. As the ring gear rotates, it deflects due to the range of normal load conditions and, consequently, the spacer 26 is quickly and totally worn away thereby producing the desired running clearance between the stop member 22 and the ring gear 20.
- the spacer of the present invention could be used to accurately space any two parts where the running clearance between them is critical. Setting the running clearance in this manner is far more economical than using feeler gauges or shim stock especially in mass produced items.
- the invention described provides an improved method for setting the running clearance between a stop member and the ring gear in an automobile differential which enables a more economical way of manufacturing the same.
